I liked Animal Spirits - the section on story as an irrational variance within the housing market ("housing never loses");

Irrational Exuberance covers a broader set of topics with relation to behavioral or otherwise traditionally irrational action; and

Identity Economics (though probably the least financial but one that inspired me quite a bit in my understanding of how behavioral and traditional principles can be/are interrelated - though the experiments are lacking and can somewhat be found in complex systems research).
